Hi, having similar issues with 12.04 (with both trusty and precise kernels).
Don't see any fixes for the trusty kernel. Tried adding trusty, but launchpad gives an oops when I try to. We have several webservers with IPv6 directly attached to internet. 2 12.04's both running with trusty kernel now and 2 16.04's. 16.04 <-> 16.04 consistently around 110MB/s (gigabit limit) Downloading on 16.04 from the 12.04 machines is horrible. Connections die, huge drops in performance (sub 1MB/s) 12 <-> 12.04 same as above. Please add fix to trusty kernel as well.
